Performance detection:
One, backing-off performance
In the test of backing-off performance, unwinding tester (PPA3) is used to be evaluated.Every test that PPA3 is provided
As a result in, with spinning cake performance factor PPF and broken end number for main evaluation index.The number that breaks end is more intuitive, in certain survey
It tries under speed, broken end number is fewer, and the backing-off performance of spinning cake is better, and data-analyzing machine reads strand with the frequency of 500Hz and moving back
Tension variation in, this tension data carry out storage processing in the form of accumulative tension distribution.After the completion of primary test,
First the data of storage are analyzed, then tension distribution characteristic is integrated and tensammetric peak calculates PPF.Test speed is
1500m/min。
Other parameters and step in comparative example 1-4 are identical as embodiment 1-4 respectively, the difference is that, raw material is straight
It connects and is added in polymerizing reactor；The other parameters and step of comparative example 5 are identical as embodiment 1, the difference is that not into
Row heat treatment without tension.
As can be seen from the above table, the polyester filament being prepared by the present invention, PPF is small, illustrates spinning cake in unwinding process
In tension fluctuation it is small, the backing-off performance for characterizing spinning cake is good；And in comparative example 1-4, raw material is added directly into without processing
In reaction unit, PPF is increased, and the number that breaks end also obviously rises, this shows that polyester filament prepared by the present invention reduces neighbouring material
Van der Waals electrostatic attraction is formed between son, and there is good spinnability；Without passing through heat treatment without tension in comparative example 5, PPF is increased,
And broken end number also obviously rises, spinnability is poor.
Two, full-dull polyester filament characteristic test
The obtained full-dull polyester filament of measurement embodiment 1-4, other steps and parameter of comparative example 1-4 respectively with reality
It is identical to apply a 1-4, the difference is that, selected raw material is conventional raw material combination: polyethylene terephthalate,
TiO2.Inherent viscosity, Dynamic Thermoelastic Stresses CV value, elongation at break detection, experimental result such as following table institute are carried out to polyester filament
Show.
Inherent viscosity: the molecular weight of PET directly affects the physical mechanical property of its spinning properties and fiber, and molecular weight is too
Low, then melt viscosity decline is excessive, and fiber is unable to undergo more powerful stretching, and spinning is easily breaked end.Inherent viscosity is low, and characterization is poly-
The weight average molecular weight for closing object is also low；Because TiO2 particle is dispersed in PET slice, destroys the regularity of molecule and reduce big
Intermolecular packing ability, causes inherent viscosity to reduce, and still, due to the unique composition of raw materials that uses of the present invention, maintains point
The regularity of son, so that packing ability ensure that the integrality of strand there is no declining between macromolecular, it is produced by the present invention
The viscosity of full-dull product has good viscosity there is no declining, and product regularity is preferable.
Elongation at break: for super fine denier full-dull polyester filament, elongation at break shows between 125-135
It is with good elongation；When the product matched using conventional raw material carries out above-mentioned parameter detection it can be found that
Its elongation at break is higher, shows that the toughness of product is poor, is easily broken.And the polyester filament obtained by the present invention, fracture
Elongation has good toughness between 127-130, not easy to break.
Three, yarn unevenness
Yarn unevenness is an important indicator of the inherent quality of POY, is directly related to the aft-loaded airfoil performance of POY, item
Dry irregularity is excessively high, and the faults such as striped and the color dot in dyeing easily occurs in process in DTY, reduces the item of full-dull POY
Dry irregularity has great significance for promoting its aft-loaded airfoil performance.Measure the item of polyester filament made from embodiment 1-4
Dry irregularity, other technological parameters of comparative example 1 are same as Example 1, the difference is that using side-blown wind process.Detection knot
Fruit is as shown in the table.
As can be seen from the above table, there is lower yarn unevenness by polyester filament produced by the present invention.Four, it rubs
Coefficient and rate of dyeing
Coefficient of friction between the silk and silk of the full-dull polyester filament that this measuring embodiment 1-4 is obtained, setting pair
Ratio 1, the parameter and production method of comparative example 1 with embodiment 1, the difference is that, comparative example 1 be triangular-section, it is right
The parameter and production method of ratio 2 with embodiment 1, the difference is that, selected raw material is conventional raw material combination: poly-
Ethylene glycol terephthalate, TiO2；The parameter and production method of comparative example 3 with embodiment 1, the difference is that, will be former
Material is added directly into polymerizing reactor.Coefficient of friction result is as shown in the table.The Grade A of the uniformity dyeing of dyeing
Rate (M rate) embodies, and the specification of DTY is 150D/288F.
| Embodiment | TiO2Content | Coefficient of friction | M rate/% |
| Embodiment 1 | 2.8 | 0.164 | 97.4 |
| Embodiment 2 | 2.9 | 0.158 | 98.2 |
| Embodiment 3 | 3.0 | 0.160 | 98.1 |
| Embodiment 4 | 2.9 | 0.162 | 98.4 |
| Comparative example 1 | 2.8 | 0.385 | 91.2 |
| Comparative example 2 | 2.8 | 0.401 | 87.4 |
| Comparative example 3 | 2.8 | 0.517 | 84.3 |
Due to TiO2In gathering for fiber surface, the surface area of fiber is caused to be declined, in mutual friction, rubbed
The area for wiping contact becomes smaller, so coefficient of friction accordingly becomes smaller, but due to TiO2Aggregation, will lead to asking for uneven dyeing
The shortcomings that inscribing, but passing through special process and material combination of the invention, avoid full-dull polyester filament, terylene obtained
Long filament coefficient of friction is small, and resistance is small, high-quality, and will not influence rate of dyeing, avoids diffusion of the dye molecule on fiber
The irregular problem with absorption.
Obviously present invention specific implementation is not subject to the restrictions described above, if use method concept of the invention and
The improvement for the various unsubstantialities that technical solution carries out, or not improved directly apply conception and technical scheme of the invention
In other occasions, within that scope of the present invention.
